Two nights in a row...bright light hovering near Sourth Mountain and then rapidly jetted away then disappeared.

Two nights in a row, saw the exact same thing. Driving home on I-10 around 6:00 pm noticed a bright light in the sky that was hovering and then jetted away at a VERY high rate of speed to the south and up and then disappeared. First time, thought it was my imagination, but saw the EXACT same thing the next night on the drive home.
